Dennis devloped a new internal gear system for the G4S that some of us got a chance to run this past weekend at Toledo. It was a very definate improvement, and I picked up about .3 sec's per lap. I also ran the new Black clutch spring with all the weights in the flyweights, and dialed a ton of clutch in it. Dennis reworked a Kyosho UFO clutch bell and pinions. The motor just came to life, and the bottom end pulls waaay harder!! The first column of numbers is the standard drive numbers, and the second is the numbers for the improved internal drive. I also undertsand in afew months Team Magic will be offering a still lower internal drive. Some of the prototype stuff I saw was really really trick!!
